"The journalist, Pushp Sharma, should not be held behind bars while he waits for the courts to adjudicate the case against him," Committee to Protect Journalist's (CPJ) Asia Programme Coordinator Bob Dietz said in a statement.
"The journalist is not a danger and he presents little risk of flight. We call on Indian authorities to release him immediately," Dietz said.
The case was registered against him after his report 'We don't recruit Muslims: Modi govt's Ayush Ministry' appeared on Milli Gazette, a fortnightly English language newspaper.
On May 16, a Delhi court sent him to 14 days' judicial custody.
